Description
Technical field
The present invention relates to a kind of top cradle of the drafting system for fine spining machine, described top cradle have at least one be applied in spring force, tension upper leather ring and at the apron guiding element that turns to edge that this upper leather ring is turned to, this apron guiding element remains on the middleware of described top cradle.
Background technology
Utility model patent document DE 92 14 598 U1 of Germany disclose a kind of claim 1 top cradle as described in the preamble, the apron guiding element that this top cradle has a tension upper leather ring and this upper leather ring is turned to, described apron guiding element remains on the middleware of described top cradle.This apron guiding element has been applied in spring force, to keep described upper leather ring with the tension force limiting.In order to guide described apron guiding element, described apron guiding element is with shaping axle journal, and described axle journal is directed in the respective channel forming on described middleware.According to DE 92 14 598 U1, described axle journal and described channel setting are at described upper leather ring in the operating path width on cradle or middleware.Now, the channel depth in described middleware is confined at this locational middleware width.
In prior art, the shortcoming of disclosed top cradle is, on apron guiding element between the axle journal of the Amplitude Ratio guiding use that turns extrorse rising and descending motion with respect to the horizontal plane and passage with manufacture relevant play amplitude and want large.The reason of this situation is that, with respect to the passage on the middleware of top cradle, apron guiding element can protrude setting.When the upper leather ring that makes to be strained by apron guiding element moves, always there is subsequently turning extrorse height change; And when making top cradle static, turn extrorse height and change inversely.With duty relatively, the tractive force occurring in upper leather ring points to different directions.This result causing is, in described upper leather ring operating period, the edge that turns to of described apron guiding element is upwards drawn, and during inactive state, the edge that turns to of described upper leather ring deflects down.Yet the lower limb of described apron guiding element is procedure parameter with respect to the deflected height of lower apron bridge shape frame or lower apron, this procedure parameter has affected the result of spinning process subsequently effectively, therefore knows that the height of deflection has very large meaning.Turn to edge to be so positioned, i.e. described upper leather ring and the operation parallel to each other of described lower apron and change their height, variation of this height is be difficult to or can not determine completely during operation.
Summary of the invention
Therefore, task of the present invention is to provide a kind of top cradle, and the feature of this top cradle is: turning extrorse changes in deflection, especially when changing the duty of upper leather ring, to turn extrorse changes in deflection very little.
First aspect present invention is by providing a kind of top cradle of the drafting system for fine spining machine to realize this task.Described top cradle have at least one be applied in spring force, tension upper leather ring and at the apron guiding element that turns to edge that this upper leather ring is turned to, this apron guiding element remains on the middleware of described top cradle, described top cradle is characterised in that, outside the operating path width of described upper leather ring, on described apron guiding element and described middleware, construct at least one pair of for guiding described apron guiding element, mutual corresponding induction element.
According to first aspect suggestion, at least one pair of is set for guiding apron guiding element, mutual corresponding induction element on the apron guiding element outside the operating path width of upper leather ring and on middleware.The main advantage of this layout is, with respect to according to the layout of prior art (induction element be arranged on apron guiding element below and and in its operating path width), for guiding the induction element of this apron guiding element can be configured to phenomenal growth.By this measure, with respect to top cradle of the prior art, length of lead of the present invention is obviously elongated, and the size that turns thus extrorse rising and descending motion is reduced, this size is reduced to the play size of the induction element of guiding use, and this play size is known and relevant to performance.As described in detail for prior art in the above, by this layout substantially avoided completely due to duty change cause turn to edge deflection.By reducing, because upper leather ring duty changes the size that turns to edge deflection causing, advantageously to have affected the result of the result of drafting process and spinning process subsequently.
For this reason, at least one induction element on described middleware can be configured to guide groove, at least one induction element on apron guiding element be configured to guide rail simultaneously.
Here, described guide groove or described guide rail are constructed to continuous.
Alternatively, the induction element that is constructed at least one guide groove can have discontinuities (Unterbrechung).
Similarly, the induction element that is constructed at least one guide rail can have discontinuities.
So be chosen in the scope of the discontinuities arranging in the horizontal plane of described guide rail and/or described guide groove, that is, and described guide groove and described guide rail overlapping at least in part without interrupting section.
Therefore, on at least one guide groove and/or at least one guide rail, should so select the layout of described discontinuities,, location-independent with apron guiding element with respect to middleware, always there is at least in part engagement with their respective segments on the guide groove being disconnected in all sections of the guide rail being disconnected, thus avoided due to duty change cause described in turn extrorse deflection.
In preferred improvement project, described guide groove can extend beyond the length range of described apron guiding element in its horizontal plane, yet is subject to possible constructions spatial limitation.This turns the size decreases of extrorse rising and descending motion described in further advantageously having affected.
Especially described guide groove can extend to the edge that turns to of apron guiding element.Thus, can reduce the bulge quantity that described apron guiding element exceeds described guide groove.Correspondingly attainable, when described guide groove turned while turning to edge described in extending beyond in an extrorse side in deviating from of described apron guiding element, described protrusion is reduced.
In a favourable embodiment, apron guiding element can be configured in two sides all with guide rail, and described middleware is configured to corresponding guide groove.The advantage of this make is: in two sides the above apron guiding element can be designed to identical, this not only to be preferably embodied as injection molding member member manufacturing cost and also the installation of top cradle is all produced to favorable influence.
Advantageously, the length of described two guide grooves can be different.This make of middleware has been simplified the installation and removal of upper leather ring.
At this, in two guide grooves on a shorter outward flange that should be arranged on described middleware, to can more easily mount and dismount described upper leather ring.

The specific embodiment
View in Fig. 1 shows top cradle 1, and this top cradle 1 comprises a middleware 2 and two apron guiding elements 3.Middleware 2 is arranged on the axle 5 of two top rollers 6.Two top rollers 6 remain on the guide rod of top roller carrying and arm in known manner.Apron guiding element 3 is relevant to the top roller 6 of two rotatable arrangements.
Unshowned upper leather ring is around top roller 6 and apron guiding element 3.At this, by the described upper leather ring of apron guiding element 3 guiding, and this upper leather ring is turning to edge to turn to.By the operating path width of the next door arranging perpendicular to the upper leather ring direction of motion 4 restriction apron guiding elements 3 on apron guiding element 3, as obviously found out from Fig. 1 to Fig. 3, can avoid thus described upper leather ring from 3 slippages of apron guiding element.In order to strain described upper leather ring, apron guiding element 3 has been applied in spring force, by the spring 7 being arranged between middleware 2 and each apron guiding element 3, produces this spring force.As shown in Figure 3, spring 7 is arranged in each interconnective circular channel 8,9 of middleware 2 and apron guiding element 3, so that protection spring 7 is to avoid contacting fibre fluff.
In order to guide apron guiding element 3, on middleware 2 and outside the operating path width of described upper leather ring, form induction element.In the embodiment shown, described induction element is constructed to guide groove 11 and the guide rail 12 outside upper leather ring operating path width.Guide groove 11 is for being contained in the corresponding guide rail 12 forming on apron guiding element 3.In addition, on the apron guiding element 3 in operating path width, axle journal 13 is set, axle journal 13 has engaging protrusion 14 at its free terminal.Axle journal 13 is engaged on the corresponding passage 15 of the operating path width that is positioned at equally upper leather ring.The position that the engaging protrusion 14 of described apron guiding element 3 is mounted to middleware 2 at it in the back with passage 15 in recess engagement.By this way, avoided when removing upper leather ring, apron guiding element 3 comes off from the mid portion 2 of top cradle 1.
As the view from Fig. 2, obviously find out, middleware 2 has than the little horizontal-extending portion in its zone line in the region that is provided with each apron guiding element 3, and it is for being fixed on the axle 5 of two top rollers 6.Cause the reason of this situation to be, in traditional top cradle 1, for guiding the axle journal 13 of apron guiding element 3 and corresponding passage 15 being restricted aspect their length, this is because described axle journal 13 and passage 15 are arranged in the upper leather ring operating path width on apron guiding element 3 or middleware 2.
By the operating path width at upper leather ring according to the present invention, arrange guide groove 11 and corresponding guide rail 12 outward, it is longer according to the passage 15 in upper leather ring operating path width and the axle journal 13 of prior art that guide groove 11 and corresponding guide rail 12 can be implemented as beguine.In addition, as Fig. 3 obviously illustrates, the front end of guide rail 12 extends in the next-door neighbour's who turns to edge 16 the region of apron guiding element 3, so the bulge quantity that apron guiding element 3 exceeds guide rail 11 reduces.By these measures, apron guiding element 3 turn to edge 16 may rise and the order of magnitude of the size play amplitude that still only the running in induction element causes of descending motion in.Thus, substantially avoided make upper leather ring when motion or when making upper leather ring static because duty changes the deflection that turns to edge 16 that the tractive force that produces causes, this tractive force points to different directions relevantly from duty.
According to available structure space, the guide groove 11 that can extend middleware 2 makes it to exceed to turn to edge 16 or surpass and deviates from a side that turns to edge 16.
In Fig. 4, illustrated top cradle 1 ' the top view of embodiment of modification, and in Fig. 5, illustrated according to the top view of the apron guiding element of the second embodiment of Fig. 4.As obviously found out from Fig. 4 and Fig. 5, in this embodiment, described induction element be middleware 2 ' on guide groove 11 ' form and being deviate from apron guiding element 3 ' a side that turns to edge 16 on guide rail 12 ' form, this induction element is lengthened out.Its advantage is, in the situation that optimization utilize top cradle 1 ' available rear structure space, due to extended exceed the induction element 11 of middleware 2 ' width ', 12 ', therefore when changing duty, surpass induction element 11 ', 12 ' between the apron guiding element 3 ' deflection of play amplitude can be reduced.
In addition, in Fig. 6, illustrated according to the apron guiding element 3 of the 3rd embodiment " perspective view, this apron guiding element 3 " guide rail 12 " is interrupted by groove 10 at least one position.Shown here guide rail 12 " implement of interruption function mode cause forming 2 supportings in guide groove 11; and this is a kind of trickle modification; this modification has guaranteed same stability, as according to Fig. 1 to Fig. 5 have strand guide 12,12 ' apron guiding element 3,3 ' scheme.Similarly, guide groove and/or guide rail also can have at least one discontinuities or groove 10.Here the interruption of guide groove can be material groove, and this material groove does not hinder strand guide 12,12 ' and guide rail 12 " the smooth locomotivity in the horizontal plane of interrupted guide groove of being interrupted by groove 10.
According to showing according to the top cradle of Fig. 11 " Fig. 7 of the 4th embodiment, middleware 2 ' have guide groove 11 ', by groove 18 piecewises of extending in horizontal plane interrupt this guide groove 11 '.In this flexible program, the strand guide 12 of apron guiding element 3 be similarly only bearing in guide groove 11 ' without on two positions on the section interrupting.
Finally, also can consider the combination of two kinds of flexible programs, in this combination, not only described guide rail but also described guide groove have the discontinuities that is form of grooves.
During operation and when changing duty, according to the apron guiding element of the 3rd or the 4th embodiment or according to the apron guiding element of these two embodiments and the combination of middleware, precondition for apron guiding element stability is: induction element always exists contact each other, to avoid apron guiding element to horizontal plane deflection.
